Why is the healer class basically a one spell dps class?

[Anhra]

This playerbase can barely handle healing in endgame content (lvl 80 dungeons). Having to dps as well would ultimately shut down their brain cells.

Sometimes, true Progress demands sacrifices to be made, in one form or another. And i hope that "mini dps rotation" means more than just 1-2 additional dps spells for lvl80+.

Healers deserve to have at least 5-6 more dps abilities from the way i see it (and with that, i mean actual skills, not just the same basic spell that just does raw dmg on single target/splash range, let us have placeable AoEs or something that channels for a few seconds).
